Abstract: We study the fluxes of anti-deuterons that could be produced by annihilationsin the galactic halo of Dark Matter particles with multi-TeV mass and a largeannihilation cross section, as indicated by the recent PAMELA results. Themodel of Minimal Dark Matter MDM is an example in this category. We find thatthe fluxes are well within the reach of planned experiments for DM candidatesthat annihilate mainly into quark pairs, and also extend into the multi-GeVrange above the background. They are instead suppressed and concentrated at toolarge energies to emerge above the background if the main annihilation channelis into gauge bosons such as in particular W+W- in the MDM case.
